CVE-2024-46760

Kernel crash via premature rtw88 USB receive work

Published Sep 18, 2024 · Updated May 11, 2026

NULL pointer dereference in the Linux rtw88 USB driver allows local users to crash the kernel during device initialization. The rtw_usb_probe path submits receive URBs before rtw_register_hw finishes initializing the hardware object used by rtw_rx_fill_rx_status. The published record identifies no attacker-controlled trigger; reachability requires the rtw88 USB receive path to run during probe.
